| abstract |
In the present invention, the surface density is 5 g / m 2 or more and 400 g / m 2 or less, and the weight is from 90% by mass in the thermogravimetric analysis measured at a heating rate of 10 ° C./min and a measurement temperature of 23 ° C. to 550 ° C. It is a polyolefin-based resin foam sheet in which the time (t) required to reduce to 10% by mass is 9 minutes or more. According to the present invention, it is possible to provide a polyolefin-based resin foam sheet having high flame retardancy while maintaining light weight. |
